Bug Description

User Query:please write a report with mails created during recent 30 days in boost mailing. only use MCP server. if it is impossible, give me error message.

Error: Cannot filter by date range using MCP server
The Pinecone MCP server has limitations that prevent filtering boost mailing messages to the last 30 days:
Metadata filter not working: When I pass a timestamp filter (e.g., {"timestamp": {"$gte": 1766880000}}), it returns "[object Object]" and no results, indicating the filter format isn't being parsed correctly.
Timestamp metadata not in results: The query results include author, content, score, etc., but not timestamp, even though the namespace metadata includes a timestamp field.
No date filtering capability: Without working metadata filters or timestamp data in results, I cannot filter to the last 30 days using only the MCP server.
